I registrated two model in slicer and get the transform but it is not the same with VTK.(The promblem may be “different coordinate system” )  
I searched the forum to deal with it by python code(get the slicer’s transformcould be import in vtk) but get nothing.  
And another problem: can I set the same coordinate system between VKT and slicer?  
Thanks.  
The different results:
